It provides,as a cost saving measure and attachment facilitating measures, anarrangement whereby the rifle butt can carry different, interchangeablebutt plates, adapting the rifle stock itself to different uses,including for example use of the rifle for skeet shooting, for shootingclay pigeons, for purposes of hunting, and other purposes, also fittingthe rifle stock for use by different hunters and other users.

For this'purpose the new rifle butt plate unit comprises an intermediateplate, directly attached to the rifle butt, and generally a set of buttplates directly or indirectly attached to the intermediate plate bysuitable fitting means. In the case of indirect attachment of the buttplate, extension pieces or anti-recoil shoes may be provided.

FIGS. 7 and 8 illustrate a second modification in views correspondingrespectively to FIGS. 2 and 1.

FIG. 9 shows a third modification in a view corresponding to FIG. 2.

FIG. 10 shows a fourth modification in a view corresponding to FIG. 1.

DETAILED DESCRIPTION As shown in FIG. 1 the shoulder end C of the riflebutt C is equipped with an intermediate plate 1, so arranged that therifle can have different butt plates secured thereto, interchangeably,without other modification of the rifle and intermediate plate. For thispurpose the rifle butt as shown has a central hollowed out portion C forhousing essential profiled part 10 of the intermediate plate I.Preferably but not necessarily the plate is of a suitable plasticmaterial. As illustrated, it is secured to butt end C by wood screws 2,the heads ofwhich are centered in countersunk recesses lb at the face ofthe plate facing away from the butt.

Central profiled piece la of the plate receives, directly or through theintermediary of threaded metallic ring 4, a machine screw 3 having ashouldered end 3a for holding the butt plate to be secured to theintermediate plate.

The butt plate 5 as shown in FIGS. 1, 2 and 4 is of the type frequentlyused for purposes of hunting or skeet" 1 shooting. Such a plate 5receives the head end of machine screw 3 in a central boss 5a. Forproper location of the butt plate the butt surface of this plate, facingthe intermediate plate, is of suitably recessed and ribbed structurewith recessed bosses 5b for engagement with the bosses 1b of theintermediate plate 1. Plate 5 is generally made fairly thin, with athickness of the order of 10 to 12 mm and with a slightly concave outersurface as encountered in many types of rifles. The plate can be ofplastic and particularly of cellulose acetate.

The modified butt plate 6 of FIGS. 5 and 6 is of a greater thickness, onthe order to 25 to 30 mm, and has more pronounced outer curvature to fitthe users shoulder. This form is particularly preferred for use onshooting ranges and the like.

According to the modifications of FIGS. 7 and 8, extension plates 7,preferably of metal, are interposed between intermediate plate I andbutt plate 5 or 6. They fit the bosses 1b of plate I and can besuperimposed on one another in suitable numbers depending in the desiredtype of rifle use.

The modification of FIG. 9 shows the use of an antirecoil butt plate 8with a shoe 9 interposed between the plates and flush with plate 1.Machine screw 3 passes through apertures in the butt plate and in theshoe. Also used are centering and locating provisions, cooperating withbosses 1b as before.

As finally shown in FIG. 10 the butt plate 8 can have a design or motifor decoration impressed thereon or raised therefrom, in part or over theentirety of its peripheral side surface.

It will be realized from the foregoing description that either one orseveral butt plates can be interchangeable on the intermediate plate 1,and different accessories such as extension plates or shoes can beprovided. This provision leads to significant reduction in the stock tobe maintained and corresponding price of the unit, while allowing fulldiversity of the types of butt plate. Also the use of a single machinescrew for fixing the butt plate to the intermediate plate facilitatesand accelerates the interchange of the butt plate on the rifle.
